MACHINE FOR FIXING HEELS T0 BOOTS AND SHOES.

Application filed May 10,

To all whom it may conce n:

Be it known that we, CHARLES ADAMS YOUNG and Josnrn HENRY Woo-omo'roN, subjects of the King of Great Britain and Ireland, and residents, respectively, of Bristol and Glevedon, both in the county of Somerset, England, have invented a certain new and useful Improvement in lilac chines for Fixing Heels to Boots and Shoes, of which the following is a specification.

The present invention relates to a machine for fixing heels to boots and shoes, hereinafter jointly referred to as shoes, in the course of manufacture.

Hitherto in fixing high shaped heels to ladies shoes, the last on which the shoe is made is withdrawn to enable the heel to be pinned on by a machine, and the last then re-inserted for the further operations required in the finishing of the shoe.

Further, under existing methods of fixing some heels of peculiar shape, such as Louis and the like, only a small part of the heel is in firm contact with the shoe.

According to this invention it is not necessary for the last to be withdrawn. The heel is cemented on the surface of its seat, placed in position, and held under pressure by the machine till such time as the cement hasset.

This effects a great improvement, the whole of the seat of the heel firmly adhering to the shoe; a further advantage being obtained by obviating the withdrawal of the last and re-inserting the same whilst the shoe is in a damp condition, thereby saving time and possibly injury to the shoe.

Further, with a machine as hereinafter set forth, no marking or damage by the adjacent metal parts of the machine occurs on the sides of the shoes, as at present obtains with existing machines.

In order that the invention may be the more readily understood, reference is to be had to the following description and accompanying sheets of drawings, wherein Figure 1 is a side view of amachine constructed in accordance with the invention, the movable parts of said machine being shown in inoperative positions.

Figure 2 is a side view, the heel and top piece fixing members being shown in action.

Figure 3 is a similar View but showing 1922. Serial No. 559,852.

both 'ieel and top piece and cemented extension iixings in action. igure at is a planview of said Figure 3, the shoe and last being omitted for clearness.

Figures 5 and 6 are, respectively, front and end views of the machine, the shoe and last also beingomitted for olearness.

Like numerals of reference indicate corresponding parts in the several figures.

in carrying out the invention, the machine comprises a base plate 1 provided with a centrally disposed pillar 2, to the upper end of which a last pin 3 is fixed, Figures 1, 2 and 3, and at the front end with a looking post at, said post at, which is in alignment with the pillar 2, having ratchet teeth 5 on its front edge, whilst at the other end of the base plate 1 there is provided another post 6, said pillar 2 and posts4 and 6 being arranged vertically in relation to the base plate 1 and forming an integral part thereof.

a frame-shaped lever 7, with handle 8 at its front end, is pivotally mounted by its slotted rear end to the rear post 6, and a self-acting pawl 9 is pivotally'mounted in a slot 10 in the handle 8, said pawl 9 engaging, when required, in the ratchet teeth 5 of the locking post 4-.

Across bar 11, the length ofwhich'corresponds to the width of the frame-shaped lever 7, as in Figures l, 5 and 6, is by its ends rigidly fixed to the upper ends of two metal straps 12, theother ends of said straps being pivotally secured to the side members of the lever 7 in a midway position therein.

.A long screw 13 with a milled head 1% is screwed into a central and screw-threaded hole 15, Figures 5 and 6, inthe cross bar 11, said screw 13 having a centrally disposed hole therein extending from end to end thereof, and in said cross bar 11 two other holes 16 are provided, one on each side of and in alignment with the central hole 1- in a longitudinal direction.

A plate 17 located below the cross bar 11 is provided with three vertically disposed pins 18, suitably spaced apart to correspond to the holes 16 in the cross bar 11 and in the screw 13, and of said pins 18, which pass easily through said holes, the centre pin 18 is longer than the side pins 18, and is at its upper end screw-threaded to Lake a nut 19 and thus hold the plate 1'? to the cross bar 11, the side pins 18 acting as guides to keep said plat 17 in relative position to the top 5 of the heel of the shoe when. in action.

This plate 17, which is the presser plate, is provided i ith a rubber pad 20 and can be raised or lowered by operating the head lei of the screw 13, the object being to allow for the di'ii'erent ghts of heels, and a short stiff compression spring 21 is placed around the centre pin 18 and between the end of the screw 13 and the top of the presser plate 1? before the pins 18 are passed through the cross bar 11 and screw 18.

Some shoes have heels which have cemented extension of the or the shoe, and it essential that this cemented entersion be held under pressure against the breast of the heel until the :nent has set. tect this, and

0 enable the machine to the mile time or opei ions. a second frame-s pod lever 22 with vertical X- t,, to each de member thereof, is

with a engage post 4: in

e lever T to the o the lever 22 e d l an inch in -s, short piece in. to the upward er heel frontor 28 are riveted to that they form a curvature ac oss the upward curve of said short piece 27. A pad 29 of felt is secured to these steel pieces and so forms as a whole flexible pad which adapts itself to the various curves of the Louis or other heel front either direction. when under pressure, without any parts touching the sides of the shoe.

The expansion springs 26 are connected the ends of the spring steel pieces 28, the other ends of said expansion spring 26 being connected to the frame-shaped lever 22 and the vertical extensions 23 thereof which sustain the flexible pad as a whole in the ma chine and in a suitable position for its operation.

In use, the shoe 30 with the last 31 in it is placed. on the lastpin 3. Figure l, fixed to the centre pillar 2 of the base plate 1. The heel 32 is cemented on the surface of its seat and placed in position on the shoe 30. The top piece 33 is also cemented and placed. on top of the heel 32. The lever 7 is held by the handle 8 and raised, and the adjustable presser plate 17 carried by the assa-(so cross bar 11 is then swung over and placed on the top piece of the heel 32 as in Fig ure 2 and the screw manipulated according to requirements. The lever 7 is then forced downwards against the action of the spring 21, hearing on the presser plate 1?, the self-acting pawl 0 engaging the ratchet teeth 5 of the locking post 4, holding the heel 32 to the shoe 30 under pressure until. the cement has set. Y

In the ca se of heels extension Figures that have cemented oi, 1 and 2, oil? the sole up the front of said heel, the lever 22 is swung over, as in Figures 3, l, 5 and 6. carrying the flexible pad on to the cemented extension 3%: and against the heel front. The lever 22 is then forced downwards against the action oi the springs 26 connectingthe pad to it, the flexible pad as a whole auto matically adjusting; itself to the heel front and held there by the engagement of the pawl with the ratchet teeth 5 of the lockinc; post in the same manner obtains with lever 7, the cemented extension being held under pressure until the cement has set.

ll desired, the machine can be used for fixing heels and top pieces only. or for his ing the ceine ,d extension of the sole to heel front or J, or for both operations at the time. Either of the levers and 22 can be readilv removed from or lined to the machine a: equired, said levers i" and 22 being pivot-a mounted on the pivot post by bolts and wing nuts I To release the shoe from the machine. the levers 7 and 22 are slightly depressed. pawls 9 and drawn out of engagement with the locking post, and then swung over away from the shoe as shown in Figure 1. and the shoe and with it the last removed from off the last pillar.
